Follow-up Comment #1:
std::size_t hash_value(map_location const & a){
std::hash<size_t> h;
return h( (a.x << 16) ^ a.y );
}
I suppose map location co-ordinates are normally non-negative integers. x and
y are both defined as signed ints and initialised to -1000 by default
(map/location.hpp:63). I don't really know what the hash_value() function is
intending to calculate - wondering if there should be some check if the
co-ordinates are negative and return something else if they are.
